iam so frustrated with apple music

Yes it happens and it's just one of several issues in Music app.

Here's the fix...

Delete that album, but don't delete the files from its folder, go to the album folder through finder and drag and drop will consolidate the splits of albums back to one.

If iTunes or music shows multiple instances of an artist or an album then what generally works is to select all related tracks and use Get Info to add say a trailing X to each of the fields that the tracks should have in common:

• For an album; Album, Album Artist, and Artist (if artist is the same for all tracks) *
• For an artist; Album Artist (and Artist unless there are guest/featured artists listed which should not be changed)

Apply the change which merges things together, then remove the excess characters. Occasionally it may help to close and reopen the application between the two renaming operations. Part of a compilation should also be set consistently.

* If tracks are to be synced to a non-iOS device there should be a common Artist and/or the album should be set as a Compilation.

Use the songs view and display the fields Album, Sort Album, Album Artist, Sort Album Artist, Artist and Sort Artist side by side so you see whether or not it is appropriate to edit Artist and if sort values could be causing any further problems. See Grouping tracks into albums for more help if required.

One further tip for really stubborn duplicates. At one point I had three lots of Various Artists in the artists view of my iTunes Match library that wouldn't respond to the usual trailing X treatment. What I found worked was to add the trailing X to start with, but then with each group that iTunes wanted to keep separate start typing a value and let iTunes autocomplete from say Var... to Various Artists. Picking from the autocomplete lists seemed to work when pasting/editing the whole value didn't.

Yes, I tried that logic, but sometimes it doesn't work, and results have been inconsistent, even if all the fields are 100% same. In some instances it worked and some it didn't. The only reliable workaround worked me all the time is

From all the multiple instances/split of any single album

• Select any track > right click > click show in finder (move the finder window to the side as you will need it later on).

• Select all the multiple instances of tracks/single album > hit delete from Library > Delete Songs > Keep Files

• Drag and drop all the songs from the finder window to your Music/iTunes app.

Music/iTunes always keep the tracks in the same folder in the finder regardless. it only messes up in the Music/iTunes app interface.

Obviously try the first option and try to consolidate them within the app as you mentioned as you will maintain play counts and all sorts of data.

See Audiobooks on iPods and Organizing audiobook chapters - Apple Community for thoughts on preparing metadata in Music before you import to Books.
